STAND.

Application iiledv February 26, 1921. Serial No. 448,223.

T all whom it may concern y Be 1t known that I, GUSTAF Annu.' NrnsoN, a citizen of the United States, and resident of Chicago, county of Cook. and State Abookkeeping machines and the like for which a firm support is required during the use of the machine, but with provision Afor permitting the stand and the load to be easily shifted from place to place when the machine is not in use. The object of the invention is to provide an improved construction y of stand or like article of furniture having casters and a simplified and easily operated mechanism for moving the casters into and out of service position.

In the accompanying drawings- Fig. 1 is a detail front elevation comprising the lower portion of a stand embodying the features yof improvement provided by the invention, the casters being shown in service position and a second position of some of the parts being indicated by dotted lines, and

Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1 with dotted lines showing the non-service position of the casters and mechanismy for controlling the same. c

The four legs of a metal stand are represented in the drawings at 10, 11, 12 and 18, respectively. These legs `are rigidly connected adjacent their lower ends as 4by side frame members 14, rear transverse brace 15 and intermediate transverse brace 16 `eX- tending between the side `frame members 1&1 at about the center of the stand from front to rear. A clear opening is thus provided betweenthe two front legs of the stand., shown at the right in Fig. 2.

While the legs of the stand are "designed to rest directl upon the Hoor, when a firm support is desired, casters 17 are provided and, as usual, these casters are equal in number to the number of legs of the stand and one caster is located adjacent'the lower end of each of said legs. To permit relative verti- Vframevmembers 14 of the stand.

`ment of the bail.

dle 22 with the transverse brace 15.

cal movement of the casters 17 a lever 18 is pivotally mounted in eachof the legs of the stand adjacent its lower end and each of the casters is swiveled in one of said levers. As shown, the levers 18 are arranged in pairs located at opposite sides of thestand, thek two levers of eachl pair extending rearwardly and forwardly respectively from the corresponding front and rear legs of vthe stand and the two levers of each pair are of `such length as to overlap at their inner ends, as at 19, Fig. 2.

ally connected with the overlapped ends 19 ofthe two pairs of levers 18 accordingly` serves for swinging all of the said levers and raising and lowering the casters 17. For this purpose the bail 20 is preferably of such height that during'its forward movement to upright position its cross piece 21 has a cam engagement with the twol side Such movement of the bail 2O is therebyl effective l to swing the levers 18 downwardly from the positions indicated by dotted lines in Fig. 2 and depress the casters 17. Furthermore, in its said upright position the two sides of the bail 20 serve as struts extending be` tween the side frame members 14@ and levers 18 to transmit the weight ofthe stand and its load to the casters 17 In the particular form of construction i il-A lustrated, a curved handle 22 is centrally applied to the cross piece 21 of the bail 2O for swinging the bail and limiting its movement in'both directions. This handle is made conveniently accessible from the front of the `stand by being curved forwardly at its up-v per end where it is provided with a ring `23 to be grasped bythe operator. n the up- I lright position of the bail 20 the handle 22 is engaged with the brace 16 which thus serves as a sto-p to limit theforward move- Rearward movement of the 'bail 20 is limited by contact of lthe hn` bviously, if the brace 16 is' so positioned as to. be engaged by the handle 22 only when the actly vertical position, contact of the handle 22 with the .brace 16 will tend to lock the Lcasters 17 againsty accidental displacement from service position.

bail 20 has moved forwardly beyond an e'X- f` 65 A bail 20 having its opposite ends pivot- 1 I claim as my invention:

The combination with tbe lege and '''rzune members of a table or tbe like, of n, level` pvoted at one end to one of tbe table lege 5 and extending inwardly therefrom, e @ester carried by tbe lever and meansvfor swing-- ing the lever in e vertical plane comprising:

a. freely swinging strut member pivotally connected to the free end of the leve-r to engage the underside of the frame members of the table and exert a, downward pressure upon the lever when the lever is in depressed position;
